Abstract

Procédé de détection in situ du dysfonctionnement d’un dispositif radiofréquence comprenant une batterie et une chaîne radiofréquence ainsi que des moyens de détermination de la tension entre la masse et un point situé entre la batterie et la chaîne radiofréquence, comprenant les étapes suivantes : on commande la chaîne radiofréquence de sorte qu’elle soit inactive, puis on mesure la tension de référence entre la batterie et la chaîne radiofréquence, on commande la chaîne radiofréquence de sorte qu’elle fonctionne selon un premier état différent de l’état de fonctionnement nominal, et différent de l’état correspondant à une chaîne radiofréquence inactive, puis on mesure une première tension entre la batterie et la chaîne radiofréquence, on commande la chaîne radiofréquence de sorte qu’elle fonctionne selon un deuxième état différent de l’état de fonctionnement nominal, et différent de l’état correspondant à une chaîne radiofréquence inactive, puis on mesure une deuxième tension entre la batterie et la chaîne radiofréquence, on détermine le rapport du courant lors du fonctionnement selon le premier état par le courant lors du fonctionnement selon le deuxième état comme étant égal au rapport de la différence entre la tension de référence et la première tension par la différence entre la tension de référence et la deuxième tension, on détermine si le rapport de courant déterminé est égal à un rapport de courants mémorisé correspondant à un fonctionnement nominal de référence de la chaîne radiofréquence, si tel n’est pas le cas, on détermine que la chaîne radiofréquence est défaillante. Figure pour l’abrégé : Fig ure 2Method for in situ detection of the malfunction of a radiofrequency device comprising a battery and a radiofrequency chain as well as means for determining the voltage between the ground and a point situated between the battery and the radiofrequency chain, comprising the following steps: the radio frequency chain so that it is inactive, then the reference voltage between the battery and the radio frequency chain is measured, the radio frequency chain is controlled so that it operates according to a first state different from the nominal operating state, and different from the state corresponding to an inactive radio frequency chain, then a first voltage is measured between the battery and the radio frequency chain, the radio frequency chain is controlled so that it operates according to a second state different from the nominal operating state , and different from the state corresponding to an inactive radiofrequency chain, then a second voltage is measured between a battery and the radiofrequency chain, the ratio of the current during operation according to the first state by the current during operation according to the second state is determined as being equal to the ratio of the difference between the reference voltage and the first voltage by the difference between the reference voltage and the second voltage, it is determined whether the determined current ratio is equal to a stored current ratio corresponding to a nominal reference operation of the radiofrequency chain, if this is not the case, it is determined that the radio frequency chain is faulty.
